I run the Tradestation charting platform on more than one computer in my home. I noticed that there are times when there are differences of historic prices of continuous futures charts ( ex; @es) from one computer to the next. For example, on the @es weekly chart there is a weekly low price of 1180 for the week of 07/18/08 on one computer while another computer shows the low for the same week as 1185. All computers have been updated to version 8.7 Is there a way to synch the data so all of my computers show an equally accurate chart?
